Keep searching there, or on craigslist. You can use searchtempest.com to specify which craigslist sites to search in. I have had good luck finding them in the southerns states (TX, OK in specific). As they get older, finding them with lower miles will be hard to find, but I wouldn't be afraid of higher miles on a well maintained truck.
Thanks, I'll check out Searchtempest. Surprisingly most of the 2LTs or 3LTs I'm finding on cars.com with with <100k miles are in the east.. Pennsylvania, New York, South Carolina. Looks like a long road trip may be in my future.
What mileage would you consider too high for a 2500, well maintained or otherwise?
